A ANEEL The Brazilian National Electric Energy Agency (ANEEL) has authorized the installation of the first building-based energy storage system (BESS) co-located with a solar power plant in the country, inaugurating a model that is expected to gain scale in the Brazilian market.
The new project will have a power output of 1.250 kW and a capacity of 5.016 kWh, associated with the Sol de Brotas 7 solar power plant, located in the municipality of Uibaí (BA). The system is part of Statkraft's portfolio and is in the commissioning phase.
The project also connects to a broader hybrid arrangement, developed in association with the Ventos de Santa Eugênia and Morro do Cruzeiro wind farm complexes, which are already in operation.
Colocated systems are characterized by the physical and operational integration between the generating plant and the storage system, with shared grid connection and metering structures.
This arrangement differs from standalone BESS projects, which operate independently, and allows for optimizing the use of generated energy, as well as increasing the flexibility and predictability of delivery to the system.
Sandoval Feitosa, the Agency's Director-General, stated during the authorization signing ceremony that the project is considered a milestone in advancing the regulatory framework and modernizing the Brazilian electricity sector.
"It's a moment of great joy because a challenge has been set for the..." ANEEL And we, once again, have fulfilled our mission. Batteries come as a medium- and short-term solution to a problem that will intensify over time,” he said.

An answer
I didn't understand. Will the injection of energy stored by BESS into the grid be allowed? It wasn't clear in the report.
